chore: release v20.0.15 - #1408

)

tagpr titles its release PRs "Release for vX.Y.Z", which fails the
check-pr-title workflow because it has no Conventional Commits type
prefix (seen on PR #1408). tagpr takes the first line of the rendered
pull request template as the PR title, so point .tagpr at a custom
template whose first line is "chore: release {{.NextVersion}}". The
rest of the template mirrors tagpr's default body, minus the unused
tag-prefix placeholder.

The template is a Go text/template, and oxfmt's markdown rewrites
break its <details> block and nested list structure, so exclude it
from treefmt.

This also restores the title style used by the previous bumpp-based
release flow ("chore: release v20.0.14").

* chore(ci): remove pullfrog because they dont serve free tokens anymore

* Restore `pullfrog.yml` workflow

* feat(statusline): show reasoning effort level next to model name (ccusage#1405)

* feat(statusline): show reasoning effort level next to model name

Claude Code 2.1.119+ includes an optional top-level effort.level field
(low, medium, high, xhigh, or max) in the statusline hook JSON,
reflecting the live /effort setting. Parse it from the hook input and
append it to the model segment, e.g. '🤖 Fable 5 (high)'.

The field is absent for models without the effort parameter and on
older Claude Code versions, in which case the statusline keeps showing
just the model label as before.

* test(statusline): add Fable 5 fixture with effort level

Adds a manual statusline fixture for the latest model shape, including
the effort.level field, plus a test-statusline-fable5 recipe wired into
test-statusline-all so the effort display can be smoke-tested from the
CLI.

* docs(statusline): document effort level next to the model name

Updates the statusline guide examples to the current model display
('Fable 5 (high)') and explains that the reasoning effort level comes
from Claude Code 2.1.119+, with a fallback example for models or
versions that do not report it.

* Revert "Restore `pullfrog.yml` workflow"

This reverts commit 04f45b0.

* fix(codex): skip forked session replay history (ccusage#1369)

* feat(json): emit modelBreakdowns in per-agent JSON reports (ccusage#1395)

Per-agent subcommands (ccusage pi|opencode|amp|hermes|... daily/weekly/
monthly/session --json) compute per-model cost breakdowns — the table
view renders them with --breakdown — but the shared per-agent JSON
serializer never emitted them, forcing JSON consumers to re-derive
model costs they cannot actually reconstruct.

Add "modelBreakdowns" to agent_summary_json, mirroring the unified
serializers (summary_json / session_summary_json). Purely additive:
every pre-existing key and value is unchanged; the codex-native
serializer (models object) is deliberately untouched.

Tests: shared-shape insta snapshot now shows populated breakdowns for
all four report kinds; pi daily JSON asserts a full single-element
breakdown array with non-zero cost (the motivating case); fixture-
driven copilot (real pricing via read_otel_file) and qwen (real JSONL
fixture line) assertions pin their entire breakdown arrays.

* fix(pi): align unified session date filtering (ccusage#1394)

* fix(pi): align unified session date filtering

* feat(unified): --sections and --by-agent for single-invocation reporting (ccusage#1396)

* feat(unified): --sections and --by-agent for single-invocation reporting

Dashboards polling ccusage today need one unified invocation per section
plus one per-agent invocation per agent — every call re-scanning all
stores. Two additive flags on the unified commands (and the bare root
invocation) collapse that to a single call:

  ccusage daily --json --sections daily,monthly,session --by-agent

--sections <csv> emits each requested grouping in one envelope from at
most TWO store scans (daily/weekly/monthly share one Daily-kind base
load; session adds one Session-kind load), one process, one pricing
load. Every section is produced by exactly the code path its standalone
command uses — load_sections delegates to the same load_rows machinery,
so section output is identical to a standalone invocation by
construction (covered by fixture equivalence tests including claude
agent-progress usage lines and codex cross-session/model-alias dedupe
cases). Envelope order is deterministic via a local ordered serializer:
invoked section first, remaining sections in canonical order, totals
last; single-section envelopes use the unchanged existing path.

--by-agent adds an "agents" array to daily/weekly/monthly rows (the
internal per-agent breakdowns, now serialized: tokens, cost, and
modelBreakdowns per agent). Session rows are already per-agent, so the
flag is a no-op there. Per-agent costs sum exactly to the combined row.

Backward compatibility: without the new flags, JSON and table output
are byte-identical to before (verified against a 20-invocation golden
matrix on real stores). Tables render requested sections sequentially;
--by-agent is JSON-only.

* refactor(unified): address review feedback on duplication and detected agents

- row_json now composes agent_json and layers on the row-level fields
  (period, metadata, agents), so the shared row shape has a single
  serialization path; output unchanged.
- Extract parse_unified_report_arg so the root, unified-command, and
  top-level-session parse sites share one --all/--sections/--by-agent
  block; the root site keeps its mark_used bookkeeping.
- Carry daily-load and session-load detected agents separately so each
  --sections table header shows the same detected list as the
  equivalent standalone invocation.

* feat(pi): named pi-format stores as config-declared agents (ccusage#1397)

* feat(pi): named pi-format stores as config-declared agents

Tools built on pi (oh-my-pi and other forks) keep pi-format session
stores at their own paths. ccusage could only read one pi path universe
and labeled everything it found as agent "pi". Declare named extra
stores in the config file:

  { "pi": { "stores": [ { "name": "omp", "path": "~/.omp/agent/sessions" } ] } }

Each named store loads through the existing pi parser and surfaces as
its OWN agent in the unified reports: rows tagged in metadata.agents,
sessions with projectPath/lastActivity like pi, model labels prefixed
"[<name>] ". Named stores are additive to the default pi store and use
the same path-list semantics (comma-separated, ~-expansion, dedupe) and
the same date-window filtering as `ccusage pi ... --pi-path`.

Costs are computed from the unprefixed model name — the configurable
store name never participates in pricing lookup (a store named "o3"
cannot fabricate o3 pricing; regression-tested), while prefixed
pricingOverrides keys are consulted first and keep working.

Config validation: names match ^[a-z][a-z0-9_-]{0,31}$, reject
collisions with built-in agents (single source of truth asserted
against the unified loader's registry), duplicates, empty paths, and
stores whose resolved paths overlap the default pi store or another
store (silent double-counting is never possible). Invalid stores error
through the same config-error path as other invalid config content.
Absent store paths yield clean empty results, like default pi.

Backward compatibility: without pi.stores configured, all output is
byte-identical to before (verified against a golden matrix on real
stores, including a known pre-existing until-day session-window quirk
in the default pi unified path, deliberately preserved here and fixed
in a separate patch). Committed config schema regenerated.

No CLI surface changes: per-agent subcommands remain a closed set;
named stores appear in unified reports only.

* fix(pi): reject nested/partial named-store path overlaps, dedupe path parsing

- Session files are collected recursively, so a named store rooted at an
  ancestor or descendant of the default pi store (or another named
  store) would ingest the same files twice under different dedupe
  identities. The resolver now rejects any overlap — equal, ancestor,
  or descendant — and partial collisions error instead of silently
  dropping the colliding path, matching the documented contract.
  Regression tests for a store nested inside the default pi path and a
  partial overlap across two stores.
- Extract a shared existing_paths helper in pi/paths.rs; the default
  and named-store variants now differ only in their path mapper, with
  the deliberate ~-expansion difference documented.
- Update config/pi docs for the stricter overlap wording.

* fix(kimi): support Kimi Code new wire format (ccusage#1362)

Kimi Code (`~/.kimi-code`) emits a new `wire.jsonl` schema that the old
adapter could not parse, so its usage was silently dropped (ccusage#1261).

- Detect `~/.kimi-code` and the deeper layout
  `sessions/<ws>/<session>/agents/<agent>/wire.jsonl` (5 path components)
  alongside the legacy 3-component layout.
- Parse top-level `type == "usage.record"` lines: camelCase token fields
  (`inputOther`, `inputCacheRead`, `inputCacheCreation`), `time` in
  milliseconds, and `model` prefixed with `kimi-code/` (stripped for
  pricing lookup). Skip cumulative `usageScope == "session"` records.
- Deserialize `time` leniently so a float- or string-encoded timestamp
  degrades to the file-mtime fallback instead of dropping the whole line.
- Walk the correct number of parents in `kimi_root_from_wire_path` for the
  deeper layout so config resolution looks at the right root.
- Keep full backward compatibility with the old StatusUpdate format.
- Update the Kimi guide and data-source docs for `~/.kimi-code`.

* perf: cache PricingMap::find() results and skip redundant opencode pricing checks (ccusage#1407)

* perf(pricing): cache PricingMap::find() results to avoid repeated fuzzy matching

PricingMap::find() does an exact HashMap lookup followed by expensive
fuzzy matching through all ~2,200 pricing entries when the exact model
name is not in the map. When adapters repeatedly query the same model
names, a large fraction of lookups miss the HashMap and trigger a full
scan of the pricing table for every call.

Add a OnceLock&lt;Mutex&lt;FxHashMap&gt;&gt; cache that memoizes find()
results by model name (including None for models not found in pricing).
Once a model name has been resolved, future lookups complete in O(1)
instead of O(n) over the pricing table.

Also add clear_find_cache() called from load_json_with_overrides(),
load_models_dev_models(), and apply_overrides() so the cache stays
consistent when the pricing table is mutated.

* perf(opencode): skip redundant missing-pricing check when cost is known

calculate_open_code_cost and missing_open_code_pricing independently
iterate through the same model candidates. When the cost calculation
already found a valid positive cost (either from a stored cost_usd
field or from pricing lookup), skip the missing-pricing check entirely
since pricing was already resolved.

* ci(release): migrate from bumpp to tagpr (ccusage#1406)

* ci(release): add tagpr release PR automation

Introduce Songmu/tagpr to manage releases via an auto-generated
release PR: every push to main creates or updates a PR that bumps all
nine workspace package.json versions (tagpr versionFile) and syncs the
Rust workspace via the new `just sync-rust-version` recipe run as
postVersionCommand. Merging the PR tags the merge commit.

GitHub Release creation and CHANGELOG.md generation are disabled in
.tagpr because changelogithub keeps generating the release notes in
the existing style.

Tags pushed with GITHUB_TOKEN do not trigger `on: push: tags`
workflows, so tagpr.yaml dispatches release.yaml explicitly with
`gh workflow run --ref <tag>`; release.yaml gains a workflow_dispatch
trigger for that purpose.

* chore(release): drop bumpp local release flow

Releases are now driven by tagpr in CI, so the local `just release`
recipe and the bumpp dependency are no longer needed. bump.config.ts
is deleted because its cargo set-version hook moved to the
`just sync-rust-version` recipe that tagpr runs as postVersionCommand.

* docs(skills): document tagpr release flow

Replace the removed `just release` recipe in the development skill
command list with a note on the tagpr release PR flow and the
minor/major bump labels.

* ci(release): gate release jobs to tag refs and isolate actions:write

Gate release.yaml build/publish/release jobs behind startsWith(github.ref, 'refs/tags/') so a workflow_dispatch from a branch cannot bypass the tag-only release flow. tagpr dispatches with --ref <tag>, so the intended path is unaffected.

Move the release dispatch out of the tagpr job into a dependent dispatch-release job that alone holds actions: write, keeping tagpr on its documented least-privilege scopes (contents/pull-requests/issues).

Co-authored-by: Codesmith <[email protected]>

* ci(release): consolidate release pipeline into tagpr workflow

Move the build/publish/release jobs from release.yaml into tagpr.yaml,
gated on the tagpr job's tag output, and delete release.yaml. Running
everything in one workflow removes the workflow_dispatch chaining that
worked around GITHUB_TOKEN-pushed tags not triggering `push: tags`
workflows, along with the dispatch-release job and its `actions: write`
grant.

The release jobs check out the freshly created tag explicitly.
changelogithub resolves the release tag with `git tag --points-at
HEAD`, not GITHUB_REF, so it picks the right release even though the
run's ref is refs/heads/main.

A failed release is retried with "Re-run failed jobs"; a full re-run
finds no new tag and skips the release jobs.

* ci(release): use Conventional Commits title for tagpr release PRs (ccusage#1409)

tagpr titles its release PRs "Release for vX.Y.Z", which fails the
check-pr-title workflow because it has no Conventional Commits type
prefix (seen on PR ccusage#1408). tagpr takes the first line of the rendered
pull request template as the PR title, so point .tagpr at a custom
template whose first line is "chore: release {{.NextVersion}}". The
rest of the template mirrors tagpr's default body, minus the unused
tag-prefix placeholder.

The template is a Go text/template, and oxfmt's markdown rewrites
break its <details> block and nested list structure, so exclude it
from treefmt.

This also restores the title style used by the previous bumpp-based
release flow ("chore: release v20.0.14").

* feat(pricing): support OpenAI two-stage pricing and add the gpt-5.6 family (ccusage#1414)

* feat(pricing): add gpt-5.6 family and OpenAI long-context tier rates

OpenAI introduced two-stage (short/long context) pricing with gpt-5.6:
requests with more than 272K input tokens are billed at higher
long-context rates. The same tier also applies to gpt-5.5, gpt-5.5-pro,
gpt-5.4, and gpt-5.4-pro on the current pricing page.

The existing tier support hardcoded the LiteLLM 200K boundary, so
Pricing gains a per-model long_context_threshold (defaulting to 200K
for LiteLLM *_above_200k_tokens data) and tiered_cost takes the
threshold as a parameter.

New built-in entries cover gpt-5.6-sol, gpt-5.6-terra, and
gpt-5.6-luna, including their cache-write rates. Long-context tier
rates live in a builtin_long_context_rates overlay that is re-applied
after every pricing load: a live LiteLLM refresh replaces whole
entries, and LiteLLM currently publishes these models with flat rates
only, so tier rates set directly on built-in entries would be silently
dropped whenever a refresh succeeds. Entries that already carry tier
rates are left untouched so upstream data wins once it exists.
Date-pinned keys such as gpt-5.5-2026-04-23 share their base model's
overlay rates.

The gpt-5.6 context limits mirror the 1,050,000-token window of the
other long-context GPT-5 flagship models until upstream data lands.

* feat(codex): bill long-context requests at OpenAI two-stage rates

OpenAI decides the pricing tier per request: once a request's input
exceeds 272K tokens, every token of that request (input, cached input,
and output) is billed at the long-context rates. Codex cost calculation
runs on per-model sums aggregated across many requests, so the tier
cannot be recovered from the totals afterwards.

CodexModelUsage now tracks the portion of tokens that came from
long-context requests. The split is recorded while token_count events
are aggregated, where each event still represents a single request,
and merged across parallel shards like the other counters.

calculate_codex_model_cost prices the aggregated usage as two
independent buckets: the short bucket at the flat rates and the long
bucket at the *_above_200k rates, falling back to the flat rates for
models without a long-context tier so their costs are unchanged. The
existing fast-speed multiplier applies to both buckets.

Report JSON and table output are unchanged; only costUSD values for
long-context requests differ.

* docs(pricing): explain all-or-nothing long-context overlay check

Codex review suggested filling missing tier fields independently when a
refreshed LiteLLM entry carries partial *_above_200k_tokens data. That
would mix rates that assume the 200K LiteLLM boundary with built-in
rates that assume the OpenAI 272K boundary under a single per-model
threshold, mispricing both tiers, so the overlay defers to upstream
entirely once any tier rate exists. Record that rationale next to the
check.

* build(perf): migrate benchmark harness to Babashka

Replace the large Nushell PR benchmark script with a Babashka implementation split by data, system, benchmark, report, and orchestration responsibilities. The new process boundary keeps argv, environment, and working-directory data explicit while preserving hyperfine, package installation, memory, size, and Markdown behavior.

Move the CI caller and profiling guidance to the executable Babashka entry point. Add focused tests behind their own Nix shebang so contributors can run the harness suite without adding Babashka to the full development shell.

* docs(agents): document implementation language choices

Route small command-oriented automation to Nushell and data-heavy, testable automation to Babashka. Keep production binaries in Rust and npm-integrated APIs in TypeScript so future tooling changes follow the same criteria used by the benchmark migration.

* test(ci): run Babashka harness tests

Execute the self-contained benchmark harness test entry point in the CI test job so changes to CLI parsing, normalization, fallback decisions, and report rendering cannot bypass pull request validation.

Normalize version-qualified Windows os.name values to win32 so native executable and package paths use the expected suffixes. Resolve relative pnpm pack filenames against the temporary destination while preserving the absolute paths emitted by current pnpm versions.

Add regression coverage for both platform normalization and relative or absolute tarball filenames.

* fix(perf): size local package fallbacks

Cover base and head source selection and verify both unavailable URLs through a committed-fixture smoke run.
